空压机的常见标示方法

发布日期:2019-04-26 作者:淮安开山机械有限公司 点击:


二十一世纪的空压机海陆争霸市场竞争激烈,消费者在选购产品时,常常将机器品质和价格列入购买标准之中。因此,将市场上所常见的各种标示方法作一说明,为保护消费者运动尽一份力。

 

  一、四种基本的标志方法

 

  1.SHIYONGMADAMALILAIBIAOSHI

 

  ZHEIZAIZAOQIKONGYAJISHUBUFADASHIHAIXINGDETONG,DANSUIZHEJISHUDEBUDUANFAZHAN,XIANZAIZONGSHISHISHIYONGXIANGTONGDEMADA,YEHUIYINYALIGAODI,KONGYAJIZHIZAOCHANGJIAJIJIXINGDAXIAOBUTONG,ERSHISHIJIKONGYAJISUOPAIDEFENGLIANGDUOGUAYOUTIANRANGZHIBIE。YINCI,MULUSHANGZHIBIAOSHIMADAMALI,SHIZUIBUFUZERENDEZUOFA。 

 

  2.SHIYONGHUOSAIBIANWEILIANG(Piston displacement)LAIBIAOSHI

 

  由于这是空压机的设计资料,只须将气缸大小乘上回转数即可,所以,这资料最容易得到,也为许多螺杆空压机厂家所用以标示。这个理论值与实际出气量之间没有一定的关系,视生产厂家的技术能力而定。

 

海陆争霸  3.SHIYONGRUQITIJI(Inlet volume)LAIBIAOSHI

 

  这种表示方法通常在入气口侧以孔径测量计(Orifice meter)来测定,目前只用来标示离心式空压机海陆争霸的大小。采用的单位用ICFM,这虽然较前二种方式准确,但因未计内部损失,故仍比实际出气量为高。

 

  4.SHIYONGZIYOUCHUQILIANG(Free air delivery)LAIBIAOSHI

  二、不同工况下表示出的实际出风量实际出风量指的是考虑了所有损耗,在空压机整机出口处(后冷却器之后)测得的出风量,通常用自由出气量(Free Air Delivery)来表示。

  三、不同压力下测试出的实际出风量

 

  SHIJICHUFENGLIANG(FAD)DESHUZHIYUCANZHAODEKONGQIZHUANGKUANGYOUGUAN,TONGSHIYEYUZAISHENMEYALIXIACESHIYOUGUAN。

 

  例如,55 kW的鲁茨鼓风机在0.5 barg时测得的实际出风量约为40 m3/min,55 kW的微油螺杆式空压机在8 barg时测得的实际出风量约为9.1m3/min,而在13 barg 时测得的实际出风量约为6.8 m3/min。

  对于喷油螺杆式空压机,如果在压力升高时仍要保持同样的实际出风量,需要增加转子的转速,同时要多消耗6~7%的马达功率。对于完全无油螺杆式空压机海陆争霸,则需要增加约10%的功率消耗。

  LIANGZHEDEBINENGFENBIESHI:

海陆争霸  B:55kW÷9.1 m3/min=6.04kW/(m3/min)

 

  (6.11-6.04)÷6.04×100%=1.16%
